Answer:
Electric fan testing
Electric fans are subjected to:
functional tests and durability tests,
tests of resistance to environmental conditions,
measurements of electrical parameters and characteristics.
Electric fan blade durability testing
The test consists of cyclic acceleration and braking of the fan’s electric propeller (blade). The test can be carried out at ambient or at elevated temperatures up to a maximum of 120°C.
We provide acquisition of temperature and rotational speed during the test.
Spin to Burst test
The test consists of accelerating the fan’s electric propeller (blade) until it bursts open. The test can be carried out at ambient or at elevated temperatures up to a maximum of 120°C.
